Thank you for sharing this Peter. I am trying to test a receiver project with very limited test equipment. You have provided the missing piece of the jigsaw, or at least one of them.
I need your wisdom for finding books about radio circuits(actual circuits) as all I can find is either RF engineering books or some basic electronic books, I need books where I can learn the tips and tricks for designing practical circuits on my bench.
I there, i was watching a video where one of these nanos picked up the very small signals even from a car key. I was thinking of getting one but can they record and capture it then see if i could interupt or flood the relevant frequeny and play it back
i like to use it when traveling with a vx7r to decode ssb. just dial the same frequency in both devices and vx7r on am mode. anything will do as an antenna on the vna. you can also use it for 6m dx cw
Maybe but you'd need a good quality RF attenuator and a calibrated RF probe or similar to measure the voltage across 50 ohm. RF leakage could be a major issue as my Nano VNA is not in a proper shielded case.
Hey! Can this TX and measure the antenna gain in the same time? Let's say I want to compare gain of few antennas on the same frequency to find the best RX one.Thanks!
@@vk3ye yep! Good idea! I saw something similar with a software named Nanovna server and a Nanovna-F v2 connected to USB, so on port1 was the TX and port 2 working like RX..I don't know if the software is working with older devices..Thanks!
Do you realise that the nano emits a square wave? So you're spattering multiple harmonics, most likely outside the ham bands. Also, are you aware of the sensitivity of these instruments to feed line capacitance? A great way to blow up a nano is to connect it unprotected to an antenna, where feedline capacitance can easily charge to a level where it blows the instrument.
I've always liked how you test devices beyond what their intended use is. That's how we learn and discover - thank for sharing this!
This thing has so many possibilities. Peter will soon have another book for sale.
Whatever I Search About Any Radio Things In TH-cam, Your Channel Pops Up, It Amazes Me That You Have ONLY 21K Subs
You don't have to set start and stop frequency to the same to get CW, you can just select "CW frequency" below that to get CW mode
Some earlier firmware releases don't have CW Freq as an option....maybe that is why he ignored that option?
About a minute in, I swear he said NanoDNA. Was that intentional?
Yes, again at 1.44...!!??
Thanks on the tips, but how to stop the transmission? After enabling CW, it is always transmits, even after turning it off/on. Thanks.
Just be careful, the output of the NanoVNA is a square wave, thus has a lot of harmonic energy. Of course, it’s very low power.
In the spirit of lilliputian test gear I'd like to see somebody feed a TinySA with such a wave.
Thank you for sharing this Peter.

Thanks a lot for this video! I had no clue this magic tool can do that! A great thing to test antennas in a distance!
Very nice to have and quite cheap to get the excellent results you get.
Yes! I was hoping this how it worked! I'm definitely getting one of these!
Very good idea a very small sweep
I just got one of these, they're some kit for the money.
Bravo, je n'avait pas pensé à cette éventualité. Merci de France.

Try any of Drew Diamond's (VK3XU) Radio projects books
you can use them as a dip meter as well peter
Really useful, just used this to set up a radio. Many thanks 😀
Great ideas. Where do you get them from! Can see this in more test scenarios now.
Either eBay, direct from China or local suppliers. Or amazon. A few different versions. H4 has bigger screen than v2.

This would be good for a simple fox hunt transmitter.
Thank you for the video. 73 from DL5CH

would it be possible to hook this up to a computer and use it as a wspr transmitter?
Love your video's
so that the nanoVNA has a fixed frequency and does not sweep, in stimulus you mark the same frequency in start and stop
Very cool, Thanks!!!
Can i use the N VNA to control a vco for spread spectrum freq hopping porposeses ?
Never tried it.
Is there a connection between the VNA and the receiver, or the signal is just transmitted? And another question, can I use it to calibrate an S-meter?
Maybe but you'd need a good quality RF attenuator and a calibrated RF probe or similar to measure the voltage across 50 ohm. RF leakage could be a major issue as my Nano VNA is not in a proper shielded case.
Hi..
what about the CH1?

I haven't tried it. But it might be possible using the bandscope function where received stations show as peaks.

Why do you set start and stop when you have cW frequency on the menu?
Earlier firmware releases don't have the CW option. Maybe he ignored it as it isn't an option on all Nano's?
Thanks, Good Information 73's
Set it to 100khz, and I use it as ESR meter.

If it only had a variable output in dB from 1mW down I wouldn't have to spend £80 on an RF signal generator :(
0:57 indead the DNA is nano ^^
👍👏👏
i loved your video, ummmah
Excellent, Just what i was looking for 73s VE2TSM
